Description

Technical Field

[0001] The utility model relates to the field of water conservancy projects, in particular to a construction platform for repairing a water-facing slope of a dam. Background Art

[0002] A dam is a water-retaining structure that intercepts water flow in rivers and canals to raise the water level or regulate the flow. It can form a reservoir, raise the water level, regulate runoff, concentrate water head, and be used for flood control, water supply, irrigation, hydroelectric power generation, and improved navigation.

[0003] The water-facing surface of the dam is likely to corrode under the impact of water storage, so the corroded parts need to be repaired and maintained. Currently, workers usually wear safety belts and move to the corroded parts of the dam, lift the required materials to the corroded parts, and then maintain the dam. This method is time-consuming and labor-intensive, with low construction efficiency and difficulty in ensuring the safety of construction workers.

[0004] The application date is 2022-05-20, and the application number is CN202210552262.3. The disclosed platform is for construction of the water-facing slope of a dam. The construction workers are on a horizontal operating flat plate, which makes it easier to carry out relevant construction operations and also improves the construction efficiency. However, this construction platform has the following defects:

[0005] 1. The universal wheel is flexible to move, but in order to solve the problem of the stability of the platform at the repair site, a suction cup is designed at the other end of the universal wheel axle. The suction cup and the universal wheel are switched through the action of the worm gear, that is, the platform switches to the universal wheel when moving, and switches to the suction cup during construction. This design structure needs to operate the universal wheel one by one when switching, which is troublesome, time-consuming and labor-intensive, affecting the construction efficiency;

[0006] 2. The adjustment structure of the support plate is complicated, the operation is troublesome, and the use is inconvenient.

[0007] Based on this, the present application provides a construction platform for repairing the water-facing slope of a dam which has a simple structure, a more reasonable design, and is easy to use. Utility Model Content
